This powerful and decidedly uncomfortable dark fantasy concerns Daphne, a serious and introspective young woman who just happens to live in Hell, being the youngest daughter of Lucifer and Lilith. Pandemonium isn’t a bad place to live—“the city shines silver, as highly polished as a wish. The streets sprawl out in complicated spirals, winding between glossy buildings”—but Daphne feels like something is missing. She could go to Earth and seduce young men like her older half-sisters (the hunt made more delicious by the danger represented by Azrael, the sadistic angel of death, and his monstrous companion, Dark Dreadful), but she feels like such sexual goings-on are beneath her. Then, her brother Obie, Hell’s most notorious do-gooder, saves Truman Flynn, a teenage suicide, from death. Witnessing the boy’s brief, painful materialization in Hell, Daphne is taken with him; when Obie disappears on Earth, she enlists Truman to help find him. Yovanoff (The Replacement) once again develops complex, believable characters as well as a supernatural milieu that feels both original and lived in. This confident tale contains moments of beauty, terror, and significant wisdom. Ages 14–up. (Nov.)■
